At present, the wiring of larger monitoring systems generally adopts optical fiber transmission, because the optical fiber jumper of security engineering not only has long transmission distance, small signal attenuation, but also has excellent anti-interference ability. Because of these advantages, more and more engineers are using fiber optics in surveillance system projects, so what are the precautions for using fiber optic cabling in surveillance systems?
Security engineering fiber jumper
First, you need to understand the characteristics of the fiber. In addition to the above, it also includes thin wire diameter, light weight, large transmission bandwidth and communication capacity, security and confidentiality, moisture resistance, high temperature resistance, corrosion resistance, etc.
Then, due to the small diameter and light weight, when routing the fiber, it is necessary to avoid bending the fiber forcibly and prevent the fiber from breaking.
When choosing a security engineering fiber optic patch cord, you must also configure the corresponding supporting products, such as fiber optic junction boxes, splice boxes, fiber optic transceivers, pigtails, couplers, etc. These require the selection of suitable fiber optic equipment according to different types of engineering requirements.
Security engineering fiber jumper application scenarios
Learn when to use optical transceivers and when to use fiber optic transceivers. These days, they're usually network cameras, and they use fiber optic transceivers to convert optical signals into digital signals that come from an RJ45 interface. Currently, there are still some monitors that are analog monitors. Optical transceivers used in analog monitoring are used to convert optical signals to signals on the BNC interface.
Multimode and singlemode fibers are available. Single mode fiber is commonly used in our monitoring projects. When purchasing equipment, you need to select equipment that supports single-mode fiber.
Fiber splicing methods are divided into hot splicing and cold splicing. The monitoring process is usually hot-melt, because the cold-joint stability is not good.
The last point is to keep the optical fiber 1-2 meters underground when routing the fiber optic patch cords for security engineering, while marking it for future commissioning and maintenance.
